FLOAT-VALVE ron DISCHARGING CONDENSED WATER,`

Specification of Letters Patent No. 10,416, datediJ'anuary 10, 1854;

T0 all whom t may concern:

Be it known that I, CALEB G'VALWORTH, of Boston, in the count-y ofSuffolk and State of Massachusetts, .have invented a new and useful orImproved Apparatus to be Used for Discharging Condensed Water from SteamPipes or Vessels; and I do hereby declare that the same is fullydescribed and represented in 'the following speciication and theaccompanying drawings, letters, figures, and references thereof. In theemployment of long lines of pipes for the conveyance of steam whetherfor heating buildings or otherwise, it often becomes desirable to removefrom them the water produced by condensation of the steam and thiswithout loss of the uncondensed steam.

To accomplish this, is the object of my paratus, of which the drawingsherewith presented exhibits a vertical and central section. t

In the said drawings, A, exhibits a closed cylinder or other propershaped vessel, having an inlet pipe, B, opening into it and an outletpipe, C, extending into and from it. The pipe,- B, is for the passage ofsteam and condensed water into `the vessel and connects with the steamexhaust pipe or vessel from which the water of condensation is to beabstracted.

Within the vessel, A, is a Vessel, D, made open at top, and so as tobe'capable of Hoating in water contained in the vessel A, when in use.Attached to the middle of the bottom of the vessel, D, and extendingabove it is a cylindrical valve, a, which is connected to another andsimilar valve, b, by crossed plates c, cl, whose respective lwidthscorrespond with the diameters of the two valves, they being equal toeach other. y

The valve, a,`works through a cylindrical aperture made through thebottom of a small outlet chamber, E, that is connected with the pipe, C,by means of a passage, f, the aperture, e, being equal in diameter tothat o-f the valve a. ber and directly over the valve, b, isan inletchamber, F, which is connected with the chamber, E, by a cylindricalvalve opening f', adapted to the valve b. The crossed plates, c, d,extend above the valve '6, in order to serve as guides to it.

The chamber F, freely communicates with the float vessel, D, by means ofa passage, g.-

Above the outlet cham-l require a very large float vessel as will be.

apparent afterthe mode of operation of the apparatus has been explained,and which I shall nowfproceed to specify. f

The vessel, D, is guided invits vertical movements bymeans of guides,It, lz, that are made to extend down'V from the top plate,

lc, of the vessel, A. A shoulder, z', is formed on each of the guides,h, the offices of these shoulders being, to arrest the'upwardmovement,of the float vessel when the'valves, a,V

b, are closed in or on their seats.

When the Vapparatus, is in use,-the lcon-k' densed water and steam flowfrom the pipe, B, into the vessel, A. The water passes down between the'flo`at,D, andthe vessel,

A, and of course lifts'the float so as to close Vthe apertures of thevalves, a, and. 6and force the oat up against theshoulders As soon as,or soon after thisfhas taken place, the water will* rise up and flowover the top of the float vessel, D, and until the y load or quantity ofwater deposited in the said vessel D, causes such vessel to sink ldownwardly and open the valves, a, b, or,

depress them .below their respective open- 1ngs,ne, f. Thls being thecase, the pressure of the Steam on the water in the vessel D,

`will force it through the openings, e, f', and

the extra valve b, its opening, f', and the chamber, F, made tocommunicate with the vessel, D, we are'enabled to employ a very smallvessel, D, and chest or vessel A, in comparison to what would berequlredwit-hout such appliances, for'were the pipe, C,-

to have a simple valve opening at its lower end to operate in connectionwith 'a valve applied to the floaty D, the vessel, D, would have to bemade large enough to hold sufficient weightV of water to overcome theeffect of the pressure of the'steam before the vessei would sink in thesurrounding Water suiciently to discharge Waterv through J@he valveopenings.

I claimk i In combination with the float, D, the 0ut let tube C, theValve a, and opening e, (orthe mechanical equivalents of said Valve, a,and opening, 6,) the second valve, (b) and opening, f', (or themechanical equivalents for such Valve, b, and openingV f,) so arrangedand 4applied tothe tube, C, and the Vessel or float, D, as to operatetocounteract the pressure on the other or jivalveya, under circumstancesand for the purpose substantially as hereinbefo-re specified.

In' testimony whereof, I have hereto set my signature this fourteenthday of May,
